Grinding noise !

[dacoolest]

Today I had to load my car with 4 people in the back seat and when i was driving the car hit the ground twice (most probably the exhaust which is replaced with a larger pipe) and after that I hear a grinding noise under the driving seat. specially when I slowly drive in the reverse gear. and when I drive in non-carpet roads.

and also I can feel it as well to the seat, like some sort of metal crashing each other.

my car is 99 wrx sti (version 5)

could that be some suspension problem? any ideas?

How hard was the catching the first time?I wonder if you have bent the exhaust towards the prop or a drive shaft and when you reverse it could be moving slightly (Maybe)

[dacoolest]

pretty hard. well, if thats the case do you think that theres a probability for the prop or the drive shaft to get damaged?

best bet is go have check while its light

[dacoolest]

thanks. i got it checked and seems like the pipe is loose and moving and making the sound.

[bugeye_bob]

nothing too serious then ?

[dacoolest]

i hope, will check after fixing it.

btw, i would like to ask something related to this incident.

is it a bad thing to load the car with 5 or 6 people ( some times my friends does that in certain situations) since the car is AWD? could overloading an AWD car damage the diff, VCD or the LSD ?

6 yes, as I am certain that would be illegal since the car is only a 5 seater with 5 seat belts.

5 should be fine. I have had 5 adults plus luggage in the boot with no problems. I wouldn't go ragging it about with that weight in it though else you'll end up having the same issue again.
